The expression is a supportive one about her spirit that she may not have had time to request and so others pray for her and acknowledge the horrible act that we may all not hold hatred in our heart and thus be drawn to evil thoughts .... etc.

Forgiveness is part of the healing process. This should not have happened. People where in the wrong place and time. The person who did this is serverly disturbed. We are all injured just by knowing about Hannah and so just an crumb of forgiveness helps a person heal.
Some may find this a useful refrence. It is popular among those that minister to a person that may be grieving.

Some describe grief to have five stages in the complete process of grieving: and forgiveness fits into that as well
There is no constant in the griefing process with time or intensity but there are distinct characteristics that describe a person's emotions as they process what they lost.
You might say, the sleuths help in the grieving process by allowing discussion. We might also find hints of the grieving dispostion as we look at the dialog over time.
Grief may be experienced in this way as an example: Starting with expressions of disbelief, then sorting information, expressing prayer and hope, .. feeling disbelief, ... expressing denial, ... anger, ...hate, ...defensiveness, .... self medicating, ....learning more, ....resolving, ... acceptance of the facts, ... compassion, ....learning to not accept the act ..... but to forgive the person for they are fallable, hope that they may change, ... finding self worth, resolving to make changes, and finally moving on.
It can take a life time with some stuck in a particular mode and they may need help to move to the next stages.
We might be reliving some personal issues as we read or participate in this forum.
So, God help us heal, help us forgive.
So, may God forgive him because we find it hard to forgive or can not forgive such a horrible act.
And just before He died .......
Corinthians 34: But Jesus was saying, "Father, forgive them; for they do not know what they are doing."
